These skaters attached a remote control spray paint can to the bottom of their skateboards. That way, whenever they would skate, a trail of paint would follow their path. It all makes for chaotically colorful artwork.

Ingeniously, the skaters chose to tag up an empty pool. Given the constant loopy back and forths that are necessary to ride a pool, the painting began to almost look like a spirograph. Look at all those circles! Oh, the colors! I just love the idea of amazing art being a byproduct of what people, or skaters, normally do. [YouTube via Neatorama]
